A day after terror strike on IAF base at Pathankot, fresh grenade blast injured four officials on Sunday morning.

Reportedly, the grenade went off during search operations by security personnel at Pathankot airbase.

The mishap took place as personnel were destroying the unexploded ammunition.

Earlier, on Saturday, heavily-armed Pakistani terrorists attempted to storm the Air Force base in Pathankote, triggering a day-long gunbattle in which three securitymen and four infiltrators were killed, days after Prime Minister Narendra Modi’s surprise stopover in Lahore.

With the obvious intention of destroying fighter jets and attack helicopters housed there, the group of terrorists in army fatigues attempted to storm the base which is barely 35 kms from the international border with Pakistan but could not penetrate deep.
